Hola Guys! We are currently trying to combine fedora with HBase/HDFS as a Data/Metadata store and after implementing a low level storage proof of concept for HDFS (https://github.com/smeg4brains/akubra-hdfs) the next step would be to have fedora write the metadata information that is currently written to a relational database to a HBase BigTable.
Thats why i have those questions: 1.) From what i've seen in the fedora code, having fedora use HBase instead of a relational DB, would encompass implementations for: - org.fcrepo.server.management.PIDGenerator - org.fcrepo.server.storage.DOManagar - org.fcrepo.server.storage.lowlevel.PathRegistry - org.fcrepo.server.utilities.rebuild.Rebuilder Is this correct or am i missing some classes/interfaces here? 2.) On the wiki there is page about the HighLevelStorage (https://wiki.duraspace.org/display/FCREPO/High+Level+Storage) which sounds a lot like the thing we would need for implementing some functionality we might need later on, like deciding where to store an object based on it's size. Can you elaborate a bit on the state of this feature? Are there already some concrete plans or even code? regards, frank -- Frank Asseg ePublishing & eScience Development & Applied Research Phone +49 7247-808-515 Fax +49 7247 808-133 [email protected] FIZ Karlsruhe – Leibniz Institute for Information Infrastructure Hermann-von-Helmholtz-Platz 1 76344 Eggenstein-Leopoldshafen, Germany http://www.fiz-karlsruhe.de/ ------------------------------------------------------- Fachinformationszentrum Karlsruhe, Gesellschaft für wissenschaftlich-technische Information mbH.
